I purchased a Sony STR-DA3000ES - 150 Watts/Channel @ 8 ohms, 7.1 Surround (Wish I would have purchased something else after further research) a while ago and wanted to buy descent speakers. Considering I am kinda new at this audiophile stuff, I was wondering if my reciever would be sufficient to push either the Klipsch F-2 or F-3 home theatre system. I read that if the reciever is under powered the speakers could possibly be damaged.
